Nose hair trimmer

ABSTRACT

A nose hair trimmer contains: an accommodating cylinder and a coupling column. The coupling column is inserted into a through hole of the accommodating cylinder, such that the coupling column is coaxial to the accommodating cylinder, and a plurality of first cutters on a top of the accommodating cylinder correspond to plural second cutters on a top of the coupling column, wherein between any two adjacent first cutters is defined a first slot, and between any two second cutters is defined a second slot, such that the coupling column rotates relative to the accommodating cylinder. Preferably, each first cutter of the accommodating cylinder has a tooth portion formed thereon.

FIELD OF THE INVENTION

The present invention relates to a nose hair trimmer which trims nosehairs and eliminates cut nose hair easily.

BACKGROUND OF THE INVENTION

A conventional nose hair trimmer contains an accommodating cylinder anda coupling column, wherein the accommodating cylinder has plural firstcutters, and the coupling column has plural second cutters, such thatthe coupling column rotates relative to the accommodating cylinder tocut nose hairs.

However, after the nose hair trimmer is inserted into a nose, it pressesthe nose hairs to a wall of the nose, and because a diameter of the noseis larger than those of the plural first and second cutters, the nosehairs cannot insert into slots among the plural first and secondcutters, thus cutting the nose hair difficultly.

Furthermore, the nose hair trimmer cannot operate after power of abattery consumes completely.

The present invention has arisen to mitigate and/or obviate theafore-described disadvantages.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide nose hairtrimmer in which the fitting sleeve is grasped by one hand, and the baseis rotated by the other hand to drive a rotation of the coupling columnwith respect to the accommodating cylinder, such that the plural secondcutters of the coupling column rotate relative to the plurality of firstcutters of the accommodating cylinder, thus trimming the nose hairs.

Further objective of the present invention is to provide nose hairtrimmer in which the accommodating cylinder is removed from the fittingsleeve and the coupling column easily to eliminate cut nose hairs,thereafter the accommodating cylinder is connected with the fittingsleeve quickly.

Another objective of the present invention is to provide nose hairtrimmer in which an electric driving apparatus is electrically connectedwith the coupling column to drive the coupling column to rotate quickly,thus cutting the nose hairs quickly.
